Overview
The “Automatic voltage regulator” element (AVR) is intended to switch a static capacitor bank breaker open and closed to regulate system voltage, load voltage, power factor, or reactive power.
For more detailed information on “Automatic voltage regulator” element, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.
